The Collapse of the Rules-Based Order: How 2025 Changed the World

When the year 2025 is written into the history books, it will be remembered as a definitive moment when the geopolitical landscape fundamentally changed. It was not a year like 1914, 1939, or 2001, when the world was thrown headlong into transcontinental conflicts. Instead, it was a year echoing 1933, when Nazi Germany first came to power; 1949, when the Soviet Union became the second nation to possess nuclear weapons and ushered in the Cold War; or 1991, when the fall of the Soviets gave way to a United States-led, unipolar world order. By all outward indicators, 2025 marks the period when the US-led global order fell apart, and the world crossed into a new chapter of history. Whether it involved the pivotal decisions made in Washington, Beijing, Moscow, and Brussels, the Earth-shaking conflicts that broke out in the Middle East, Africa, and South Asia, or the rise of new geopolitical players on the international stage, the events of 2025 will ripple across decades. The old, rules-based international order is unequivocally defunct, establishing 2025 as the year the new geopolitical rule book was written.

Key Takeaways

The United States intentionally stepped down from its unipolar leadership role in 2025, triggering the collapse of the rules-based global order.
Europe committed to spending at least five percent of GDP on defense, pivoting toward strategic autonomy due to strained US relations.
Japan initiated significant remilitarization efforts and mainstreamed discussions of nuclear acquisition following shifts in American Indo-Pacific guarantees.
The dismantling of USAID created massive humanitarian aid gaps, with projections indicating up to 14 million preventable deaths by 2030.
China leveraged the US withdrawal by expanding its global economic alternatives, heavily investing in AI, and intensifying pressure on Taiwan and the Philippines.
Regional powers like the UAE, Israel, and Turkey successfully pursued aggressive localized objectives free from the threat of unified international intervention.

The Historical Context of the Unipolar Order

To understand the magnitude of this historic inflection point, it is necessary to examine the world that existed before the pivotal events of 2025. At the start of the year, the Earth was dominated by a US-led, unipolar, rules-based international order. Since the conclusion of the Cold War, the United States had operated as far and away the most powerful nation on Earth. It was far more established and influential than a rising China, just as nuclear-armed as Russia but with an exponentially larger and more advanced economy, and unburdened by the military atrophy or bureaucratic dithering that characterized the nations of Europe. The United States utilized that power to back up global coalitions across Europe and the Indo-Pacific, holding tremendous sway over less-developed countries in Asia, Africa, Latin America, and the Middle East. Instead of pursuing territorial conquest, Washington placed itself at the center of global institutions, including the United Nations, the International Monetary Fund, the World Bank, the G7, the G20, and the international justice system, while simultaneously acting as the single largest humanitarian donor on Earth. Under the system it oversaw, the United States functioned as both an essential security guarantor for its allies and a practically unbeatable military and economic deterrent. This posture forced rising challengers to bide their time and encouraged upstarts to think twice before risking stepping out of line. From the perspective of America and its close global allies, this was a time of unprecedented peace, global order, and the mutual betterment of all people. From the 1990s until the 2020s, it largely appeared as if the world had grown past its base instinct to make war. Old-world strongmen like Vladimir Putin, or the isolated regimes in Pyongyang and Tehran, might have resented the new way of doing things, but they were widely viewed as outliers. The prevailing belief was that, with enough time and persuasion, they would eventually fall in line. Meanwhile, the rest of the world focused on breaking down barriers, intertwining the trade and finance of entire continents, evolving past borders and fossil fuels, and sharing the resources of wealthy nations to benevolently improve the lot of all people. However, stepping outside this predominantly Western bubble revealed that the US-led order looked profoundly different from other angles. To Putin, the US-led order was not an improvement; it was an attempt to prevent Russia from realizing its true strength after the collapse of the USSR, an event Putin famously described in 2005 as the greatest geopolitical catastrophe of the century. To Tehran and Pyongyang, it represented the United States picking winners and losers, actively attempting to strip away the losers’ power to punish them relentlessly.

The Underlying Fractures of the Rules-Based System

Even though numerous nations participated in the US-led order, that participation did not mean they considered themselves part of it, nor did it imply a desire to maintain it. To China, the US-led order represented the dominance of a superpower that needed to be challenged, a task Beijing was rapidly preparing to undertake. To rising powers like India and Brazil, the framework was an attempt to assert a single way of doing things upon nations that preferred to chart their own sovereign paths. To strategically vital nations stuck on the periphery—such as Turkey, Saudi Arabia, Azerbaijan, and the United Arab Emirates—the US-led order offered a lucrative mechanism to generate wealth, but it did nothing to satisfy their broader geopolitical ambitions. The developing nations, known collectively as the Global South, were frequently left out of major global decisions, even when those decisions carried severe implications for their own populations. Simultaneously, populations within the United States and its closely aligned allied nations often found that the reality of America's world order failed to align with its advertised benefits. Globalization proved to be a highly painful process. Global migration fostered immense political friction alongside economic opportunity, and as the power of pure capital increased, the economic stability of working classes deteriorated, regardless of geography. There were ample warning signs over the preceding decades—vulnerabilities the US and its allies could have addressed had they recognized them. Russia’s persistent pursuit of its territorial goals in Ukraine over the preceding decade, alongside the relentless dedication of Iran and North Korea to their respective nuclear programs, clearly indicated that American tools of deterrence were failing. The rapid enthusiasm with which developing nations embraced China’s Belt and Road Initiative further suggested deep dissatisfaction with the global economic structure imposed by the West. Additionally, the swell of populist movements across North America, Europe, Latin America, and elsewhere—united primarily by a profound dedication to standing against the political establishment—highlighted severe domestic discontent with the prevailing order. Building a rules-based international order inherently requires all sides to play by the rules: utilizing institutions like the UN or the International Court of Justice to settle differences, supporting common global laws, and prioritizing global betterment over individual national interests. However, for decades, the US and its allies were virtually the only nations holding themselves to that standard, and even their commitment was highly inconsistent. While the West attempted to enforce these rules, nations looking for a different path were adaptable, creative, and persistent, moving far faster than bloated democratic bureaucracies could manage. The year 2025 marked the moment when this untenable dynamic finally ruptured.

America's Intentional Withdrawal and the Trump Doctrine

If 2025 is recorded as the year the US-led, post-Cold War global order met its demise, future historians will emphasize the profound irony that the United States itself drove the final nail into the coffin. This shift was officially catalyzed by the administration that took power in Washington, D.C., on the twentieth of January 2025, under President Donald Trump. The United States' near-complete withdrawal from its former status as a global superpower was not the result of a strategic misstep or bureaucratic incompetence. Stepping back from that leading role was a central, deliberate pillar of the administration's guiding philosophy and a core tenet of the political movement that secured the second term. The administration capitalized on the economic and social discontent brewing domestically and abroad, operating on the fundamental premise that the US-led order was no longer functioning to the benefit of American citizens. From a security perspective, 2025 witnessed an unprecedented disruption to America’s network of global alliances, most notably regarding the NATO alliance in Europe and major spheres of influence in the Indo-Pacific. The administration returned to power after years of criticizing NATO, openly acknowledging past threats to withdraw from the bloc, and maintaining an overtly ambiguous stance on Article 5—the foundational guarantee that an attack on one member is an attack on all. This ambiguity severely strained relations, exacerbated by repeated threats to annex Canada or take over Greenland, currently an autonomous territory of Denmark. Although Washington subsequently reiterated a desire to stand with Article 5 commitments, it sustained an intense pressure campaign regarding security spending, threatening to withhold support if members failed to meet financial obligations. Furthermore, after years of backing Ukraine’s defense against Russia, the US shifted its posture dramatically. The administration demonstrated a degree of support for Russia that unnerved NATO leaders, punctuated by a highly publicized Oval Office meeting where Ukrainian President Volodymyr Zelenskyy was aggressively berated. By shaking the foundational trust of European allies, Washington inadvertently set the continent on an accelerated path toward strategic autonomy. This shock to the system catalyzed tangible defense shifts: Europe planned to have its nations spending at or above five percent of their GDP on defense within a few years, and many European nations began building a coalition to support Ukraine with minimal US involvement. The European Union identified alternative mechanisms to sustain Ukraine’s war effort, while initiatives to reinvigorate the continent's defense-industrial complex rapidly gained momentum. Although the US extended a NATO-style security guarantee to Ukraine contingent upon a peace deal with Russia—despite Ukraine remaining outside the formal alliance structure—these moves were inherently reactive. Europe had already begun decoupling its long-term security architecture from American political volatility.

The Ripple Effects Across the Indo-Pacific and Global Institutions

The aftershocks of Washington's pivot rippled forcefully outward to the Indo-Pacific, fundamentally altering the strategic calculus of nations like Japan, Australia, and South Korea. Leaders in these countries confronted the reality that the United States might not provide military support in a severe crisis. Just as in Europe, Indo-Pacific capitals concluded they had to prepare for the worst and adjust to a paradigm absent reliable American salvation. This realization sparked unprecedented security policy shifts, particularly in Japan. After nearly a century of strict non-militarism and staunch opposition to nuclear weapons, Tokyo began aggressive remilitarization preparations, and domestic discussions regarding the acquisition of a Japanese nuclear arsenal entered the mainstream. Similar nuclearization dialogues gained traction in South Korea, while Australia accelerated its rearmament programs, and less dominant nations like the Philippines sought protective alliances outside the traditional American security umbrella. Despite these structural fractures, signs of selective US engagement remained. Washington deepened its ties with Taiwan, authorizing its largest single sale of weapons to the island to date, and deployed nuclear-capable bombers to join Japan in a coordinated show of force against China in December. However, the overarching geopolitical foundation had irreparably shifted. Prior to 2025, allied defense strategies rested entirely on the certainty of American military intervention; the evaporation of that certainty permanently altered future strategic decision-making. Beyond military alliances, the shock to the international economic system was equally severe. The haphazard imposition of global tariffs dismantled decades of established trade policy, demonstrating an abandonment of conventional economic leverage. Previously, the US tolerated trade deficits because its immense wealth allowed it to subsidize the economic dependence of partner nations. With that approach discarded, allied economies built around American trade parameters were left to navigate a sudden, volatile vacuum. The dismantling of international institutions further accelerated the global reordering. USAID, once the world’s largest foreign aid agency and a vital instrument of American soft power, was effectively dismantled. This created immense humanitarian aid gaps that no alternative donor could fill. Epidemiological estimates suggested nearly 700,000 people died globally due to the USAID shutdown—two-thirds of them children—with projections indicating up to 14 million preventable deaths by 2030. Concurrently, Washington threatened sanctions against the International Criminal Court, withdrew from UNESCO and the World Health Organization, withheld contributions to the World Trade Organization, and reportedly explored replacing the G7 with a "Core Five" framework encompassing the US, Russia, India, China, and Japan. This sweeping withdrawal cemented a global landscape driven strictly by transactional diplomacy, where flattery, gifts, and the promise of profit became paramount, exemplified by Qatar gifting Trump a $400 million jet and major nations overlooking human rights abuses to secure trade concessions.

The Rise of Multipolarity and Regional Power Dynamics

With the dismantling of the post-Cold War monolith, the global playing field leveled dramatically, ushering in an era defined by multipolarity. In this multipolar reality, global authority is no longer dictated by a single superpower or bifurcated by a binary Cold War structure. Instead, the world is divided among several major centers of power, resulting in a highly unstable environment characterized by constantly shifting alliances. The United States remains the wealthiest nation, but China has moved within striking distance. A fractured but resource-rich Europe stands alone, while nations like Russia, Japan, India, South Korea, Australia, Saudi Arabia, Indonesia, and Brazil fiercely compete for regional dominance. Five key poles of power define this new landscape: the US and China occupy the top military and economic tiers, Europe controls tremendous collective wealth, Russia projects influence through its massive nuclear arsenal, and India leads the non-aligned bloc as the world’s most populous nation and sixth-largest economy. China reacted to America’s diminishing global footprint by aggressively expanding into the resulting vacuum. Beijing capitalized on Washington’s global tariff imposition, offering its own economic alternatives to nations struggling to accommodate American demands. Concurrently, China exerted greater leverage over rare Earth minerals, accelerated its pursuit of artificial intelligence and advanced semiconductor technology, and unveiled cutting-edge military hardware at a stunning pace. Beijing demonstrated its might through a spectacular global military parade, exerted overt leverage in Myanmar, escalated confrontations with the Philippines, and eagerly engaged in rhetorical clashes with Japan’s newly elected leadership. Simultaneously, Russia exploited the transatlantic divide by intensifying hybrid warfare against the European continent. Moscow deployed drones and armed fighter jets over NATO airspace, engaged in widespread sabotage, and openly surveilled American nuclear sites and critical fiber-optic sea cables. Regional powers proved exceptionally adept at exploiting this fractured international environment. The United Arab Emirates expanded an intricate proxy network across Africa and the Middle East, with its proxy forces seizing control of most of Yemen and perpetrating an ongoing genocide in Sudan. Israel took unilateral action to attack Iran directly and aggressively target Iranian proxy networks, operating with broad latitude despite nominal ceasefire agreements governing Gaza and Lebanon. Turkey concurrently expanded its own proxy networks and arms exports, positioning itself for a regional cold war against Israel. In South Asia, India and Pakistan engaged in direct military conflict, while Pakistan's de facto military leadership consolidated power and aligned closer to Washington. Morocco asserted definitive control over the Western Sahara, Azerbaijan secured a decisive victory over Armenia, and Thailand launched an offensive to neutralize threats from Cambodia. The fragmentation of global authority allowed regional actors to pursue localized objectives entirely free from the threat of unified international intervention.

Implications for Modern Warfare and the Fragility of Peace

Beyond immediate geopolitical realignments, 2025 clarified the rapid, devastating evolution of modern warfare and the growing fragility of international peace. The conflict in Ukraine had previously demonstrated the critical role of drones, but 2025 proved that autonomous technology could consistently outpace countermeasures. Russian and Ukrainian forces expanded beyond aerial platforms, heavily utilizing sea, undersea, and land-based drones. Ukrainian unmanned systems successfully targeted submarines below the waterline, bombed the decks of Russian shadow tankers, and inflicted massive daily casualties. This highly adaptable drone technology proliferated globally, falling into the hands of non-state insurgencies and organized criminal syndicates, forcing nations historically reliant on expensive, high-tech armor to fundamentally reevaluate their military doctrines. This technological shift coincided with a massive, global rearmament drive. The European continent, the Indo-Pacific, Central and South Asia, the Middle East, and sub-Saharan Africa all initiated sweeping defense expansions. While China produced advanced military hardware at an unmatched velocity, secondary powers like South Korea and Turkey capitalized on the surging demand for cost-effective munitions and autonomous systems. Complex, decades-long equipment sustainment contracts emerged as the primary indicators of long-term strategic alliances in the new multipolar order. Simultaneously, the nature of diplomatic resolution deteriorated. The United States abandoned its historical role in brokering enduring peace agreements, opting instead for hastily arranged, highly limited ceasefires that warring parties routinely violated. Treaties between India and Pakistan ignored the root causes of their conflict, including India's strategic suspension of water-sharing agreements. Ceasefires governing Thailand and Cambodia, as well as the eastern Congo, collapsed almost immediately as factions continued ground offensives. The societal toll of these intersecting crises became impossible to ignore. A wave of Gen-Z-led social uprisings, previewed in nations like Serbia and Bangladesh, erupted across all six populated continents, challenging or overthrowing multiple governments. These movements were unified by deep grievances over rising youth unemployment, extreme wealth concentration, and the pervasive corruption of the global elite. Concurrently, anti-migrant sentiment intensified globally, driven by mass deportations in the US and the forced repatriation of refugees to unstable regions like Syria and Afghanistan. The escalation of climate disasters met a brazen abandonment of climate-relief efforts by major powers, even as the global AI boom drastically increased energy demands. As the international order dissolved into a system where raw, transactional self-interest reigned supreme, the institutional safety nets designed to prevent global catastrophe were dismantled. The events of 2025 codified a brutal new paradigm where might makes right, establishing a highly volatile trajectory for the coming decades.
